HomeServicesTunnel and Pipe Rehabilitation

Functioning underground infrastructure is essential to our well-being. Most of us do not think much about it until problems arise. Caring for our nation’s underground assets, often decades old and in need of repair, is an ongoing challenge that water, wastewater and stormwater utility owners contend with each day. Our Pipe and Tunnel Rehabilitation Team has extensive knowledge of pipe material properties and its composite relationship with system stiffness, soil/structure interaction, constructability, and the benefits and limitations of various technologies which can help you rehabilitate and reinforce your subsurface assets.

Design of rehabilitation methods include: cured-in-place pipe (CIPP); diameter reduction (swadgelining), sliplining, pipe bursting, spincast geopolymer, spirally wound steel reinforced PVC liner, fiber reinforced polymer, UV cured polymer and shotcrete.
